Thread: How would i do this work out?

Thank you, now off to the second problem. lol

I appreciate your time and help.

Cross multiplying is when you multiply by 1 but change 1 to the form a/a where a is the bottom of the other fraction:



First multiply by to give a denominator of 12. This will make it easier to multiply later



As the last two terms have an equal denominator we can combine and simplify



Now we multiply each by the other's denominator to give them the same denominator





Now they have the same denominator we can combine



which is the answer

I still don't get it. is there a step by step tut i can use or video of some sort? I searched and google but did not come across problems as similar as mine i greatly appreciate it.

What term would be used when doing such problems?
